zioiaims. (011251-39) This invention =relates'- to valve mechanisms zand-vinits more speciflc-saspects .-is directed to a '=val-ve-- oper-atingmechanism -:suitable :for use on transformers;

ThWObjec't-df-t'thi's invention is to provide a valve to close the openings leading to and from a transformei taiik irito oiie or' niore of its cooling radiators in order to .interruptthe. interchange of' oil 'b'etweeh the'tr'ansformer-andtheradiators, thereby making it possible to remove the radiators from the tr ansiormer without any -loss of oil in the transformer tank and-to provide a quick,-accurate; positive adjustment oflthe'valve.

The shaft is suitably supported Figure 4 is a view of the valve similar to Figure 3 but in open position; and

Figure 5 shows the valve assembled on a transformer tank.

Large transformers are usually dismantled when shipped. This is particularly necessary with respect to the cooling radiators because they project from the transformer tank assembly and if allowed to remain thereon, would subject the same to the likelihood of breakage. It has been customary in the art to place a valve somewhere between the transformer tank and each of the radiators to facilitate dismantling and to enable disassembly of the radiators. Certain difiiculties have arisen with respect to the use of these valves which subject them to leakage and difiiculty of operation. This invention has been conceived, therefore, to overcome the difiiculties of the prior art structures.

The objects and advantages set forth above are obtained in the structure shown in the several figures of the drawings in which numeral I is a section of a transformer tank to which a valve 2 is secured, as by welding. A fitting 3 is connected to the valve for supporting a radiator 4 through a suitable fixture 5 cooperating with fitting 3 which interiorly connects the radiator with the transformer tank. Fitting 3 is secured to the valve by means of a plurality of bolts 6 which are removed whenever it is necessary to disassemble radiator 4 from the transformer tank I.

The valve 2 comprises a cylindrical body member I suitably apertured at 8 in which the movable valve member 9 is axially slidable. The movable member has a plurality of guides l0 thereon and packed by means of a bushing 28 and a packing 2! to prevent the loss of oil in fitting 3 past shaft 24 when the valve is open. The body member 1 is provided with suitable apertures 28 and 29 which are adapted to selectively receive screw 30 threaded into the crank or handle 25. When the crank or handle 25 is turned to closed position, screw 30 is received in aperture 28 in order to lock the valve in closed position and when it is turned to open position, the screw is received in aperture 29 to lock the valve in open position.

In order to efiect the opening and closing of the valve by means of the rotation of shaft 24, a pair of eccentrics 3i and 32 are provided thereon held apart by member 33. A collar 34 associated with the eccentric assembly has a conventional pin provided therein to lock it to the shaft so that it will hold the eccentrics in position. The proper adjustment of the valve is made by turning shaft 24 so that the valve is closed and then inserting screw 30 in aperture 28 and after this step has been accomplished, the lock nuts 22 and 23 are loosened. whereupon nuts 20 and 2! are turned to apply proper pressure between member I l and valve seat la to assure a tight, leakproof fit at this particular point. When this pressure has been applied, lock nuts 22 and 23 are tightened to lock the assembly in that adjustment. The springs l1 and 18 on studs 13 and i4 urge bridge member l9 into engagement with nuts 20 and 2|- and insure the proper spacing between the bridging members and valve member. During subsequent openings and closings of the valve by rotating shaft 24 and crank 25, the valve will always be properly closed, thereby eliminating any possibility of leakage at that point. The valve is shown in closed position in Figures 2 and 3 and in open position in Figure 4. When in closed position, the eccentrics 3| and 32 engage the inner surface of the head portion I9a of member l9 and when the valve is in open position, the eccentrics will engage the surface 9a of the movable member 9. As particularly shown in Figures 2, 3, and 4, the valve member is dished with the engageable surface So on the dished portion.

From the foregoing it is evident that a valve mechanism has been provided which is simple in its operation, positive in its action, and after adjustment will assure a perfect closure of the valve by obviating the necessity of an operator determining whether or not the valve is properly closed, this having been initially determined by the adjustment of the spacing between valve member 1 and bridge member 9 by nuts 20 and 2|.

Having fully described my invention, that which I claim as novel and desire to protect by Letters Patent of the United States is:

1. A valve comprising a body member provided with a valve seat; a valve member having a portion engageable with said seat; a pair of studs on said valve member; a bridging member provided with apertures through which the studs extend; resilient means associated with each stud to maintain said bridging member in predetermined spaced relation with said valve member; a shaft rotatably mounted in said body member and disposed between said bridging member and said valve member; eccentric means on said shaft engageable with said valve member to open the valve and engageable with said bridging member to close the valve; and a nut on each stud in engagement with said bridging member to adjust the'spacing between said bridging member and said valve member to thereby adjust the pressure between the seat engaging portion of the valve member and said seat when the valve is in closed position.

2. A'valve member comprising a body member provided with a valve seat; a valve member provided with a sealing member which is engageable with said valve seat; a pair of studs secured to said valve member; a bridging member provided with apertures through which said studs extend; a spring on each stud to space said bridging member from said valve member; a shaft rotatably mounted in said body member and disposed between said valve member and said bridging member; eccentrics on said shaft engageable with said bridging member to close the valve and engageable with said valve member to open the valve; and a nut on each stud in engagement with said bridgin member to adjust the spacing between said bridging member and said valve member to thereby adjust the pressure between said seal and said valve seat when the valve is in closed position.
